if the ball flight and results are acceptable, why is this bad?

Three dimensional impact (down, out, forward) is desired to get maximum compression which results in more power and a more controllable trajectory.

bergsey: This issue could be as simple as ball position. Ensure you are setting up with your low point (left shoulder) ahead of the ball. Another cause could be that you are not maintaining a flat left wrist at impact. I've seen guys "flip" at the ball which will scoop it instead of hitting down properly and taking a divot.

Make sure your set up is correct. Then start by hitting some short pitch shots where you finish with both arms straight and a follow though no further than waist high. Concentrate on down, out, and forward. You should be taking divots with this procedure. The divots should be in front of the ball. See 12-5-2 Aquired Motion.
